Abstract

An electronic percussion instrument including: a detecting section which is provided in a stick and detects acceleration and angular speed based on movement of the stick; a first timing generating section which generates beat timing based on a predetermined tempo and beat width; a first pre-sound-production movement detecting section which detects a pre-sound-production movement that is performed prior to sound production, based on the acceleration and the angular speed detected by the detecting section; and a sound production instructing section which instructs to produce a sound at the beat timing generated by the first timing generating section, when the first pre-sound-production movement detecting section detects the pre-sound-production movement.

Claims

1. An electronic percussion instrument comprising:

a detecting section which is provided in a stick and detects acceleration and angular speed based on movement of the stick;

a first timing generating section which generates beat timing based on a predetermined tempo and beat width;

a first pre-sound-production movement detecting section which detects a pre-sound-production movement that is performed prior to sound production, based on the acceleration and the angular speed detected by the detecting section; and

a sound production instructing section which instructs to produce a sound at the beat timing generated by the first timing generating section, when the first pre-sound-production movement detecting section detects the pre-sound-production movement.

2. The electronic percussion instrument according to claim 1, wherein the first pre-sound-production movement detecting section detects movement of the stick being swung downward from the acceleration and the angular speed detected by the detecting section.

3. The electronic percussion instrument according to claim 1, wherein the sound production instructing section instructs to produce the sound at the beat timing generated by the first timing generating section, after the first pre-sound-production movement detecting section detects the pre-sound-production movement.

4. The electronic percussion instrument according to claim 1 comprising:

a first judging section which judges whether or not the first pre-sound-production movement detecting section has detected the pre-sound-production movement between a preceding beat timing and a current beat timing;

wherein the sound production instructing section instructs to produce the sound when the first judging section judges that the pre-sound-production movement has been detected.

5. An electronic percussion instrument comprising:

a stick and a main body section;

wherein the stick includes;

a detecting section which detects acceleration and angular speed based on movement of the stick;

a second timing generating section which generates beat timing based on a predetermined tempo and beat width;

a second pre-sound-production movement detecting section which detects a pre-sound-production movement that is performed prior to sound production, based on the acceleration and the angular speed detected by the detecting section;

a second judging section which judges whether or not the second pre-sound-production movement detecting section has detected the pre-sound-production movement between predetermined amount of time before a preceding beat timing and a predetermined amount of time before a current beat timing; and

a transmitting section which transmits a pre-sound-production movement detection signal, when the second judging section judges that the pre-sound-production movement has been detected; and

the main body section includes;

a receiving section which receives the pre-sound-production movement detection signal transmitted from the stick;
